The anime world is buzzing with excitement over the latest installment in the Demon Slayer: Kimetsu no Yaiba franchise, but not all news is positive. On July 18, 2025, the highly anticipated Demon Slayer: Kimetsu no Yaiba – Infinity Castle trilogy kicked off with its first film, drawing massive crowds in Japan. However, the premiere was overshadowed by a piracy incident that led to the arrest of a 24-year-old man. This case highlights the ongoing battle against illegal recordings in theaters, a problem that affects creators and fans worldwide. In this post, we’ll dive into the details of the arrest, the impact of piracy on the anime industry, and why respecting intellectual property is crucial for sustaining global entertainment. Whether you’re a die-hard Demon Slayer fan or new to anime, understanding these issues can help foster a more ethical viewing culture.
The Arrest: What Happened on Opening Day?
On July 18, 2025—the exact release date of Demon Slayer: Kimetsu no Yaiba – Infinity Castle Part 1: Akaza Returns in Japanese theaters—a 24-year-old vocational school student named Shim Jun-woo, a South Korean national residing in Tokyo’s Adachi Ward, was accused of illegally recording the entire movie. The incident took place at a cinema in Shinjuku Ward, Tokyo, where Shim allegedly used his smartphone to capture the full 2-hour-and-35-minute film. This act, known as camcording, violates Japan’s Copyright Act and the Anti-Movie Piracy Law, which prohibit unauthorized recordings in theaters to prevent illegal distribution.
According to the Tokyo Metropolitan Police Department’s Otsuka Station, Shim denied the allegations, stating, “I didn’t camcord.” However, the evidence surfaced during an unrelated investigation. Shim had been arrested on July 30, 2025, for theft and fraud after using stolen credit card information to buy 200 anime Blu-ray discs worth approximately 1.3 million yen (about $8,800 USD) from an online retailer. During the search of his seized smartphone, authorities discovered the pirated footage of the Demon Slayer movie, leading to his re-arrest on copyright infringement charges. Police are now probing deeper into the motives and circumstances, including whether the recording was for personal use or intended for online sharing.
This isn’t an isolated event; similar piracy attempts have plagued popular anime releases in the past. For instance, bootleg DVDs and unauthorized streams of earlier Demon Slayer content have resulted in arrests, underscoring the franchise’s vulnerability due to its massive popularity.
Demon Slayer’s Global Phenomenon and the Infinity Castle Trilogy
Demon Slayer: Kimetsu no Yaiba, created by Koyoharu Gotouge, has become a cultural powerhouse since its manga debut in 2016 and anime adaptation in 2019. The story follows Tanjiro Kamado, a young demon slayer fighting to save his sister and avenge his family. Its blend of intense action, emotional depth, and stunning animation has captivated audiences internationally, with the previous film Mugen Train (2020) becoming Japan’s highest-grossing movie ever, earning over 40 billion yen domestically.
The Infinity Castle arc, adapted into a three-part movie trilogy, marks the epic finale. The first film premiered in Japan on July 18, 2025, and is set for international releases starting in August, with U.S. and Canadian screenings on September 12, 2025. Fans eagerly awaited this chapter, which features high-stakes battles in a labyrinthine demon fortress, including the return of the formidable Upper Rank demon Akaza. Early box office reports indicate strong performance, but piracy threats loomed large. Just a week after release, the official Demon Slayer team issued warnings in multiple languages against illegal recordings, emphasizing potential civil and criminal actions.
For non-native readers, anime like Demon Slayer represents more than entertainment—it’s a gateway to Japanese culture, exploring themes of resilience, family, and justice. The franchise’s success has boosted tourism and merchandise sales, but incidents like this arrest remind us of the fragile ecosystem supporting creators.
The Broader Impact of Piracy on the Anime Industry
Piracy isn’t just a victimless crime; it inflicts massive financial damage. In Japan, manga and anime piracy caused an estimated $12.5 billion loss in 2023 alone, with English-language platforms contributing significantly. The anime sector faces losses between 906.5 billion to 1.4 trillion yen annually, leading to budget cuts, reduced production quality, and fewer opportunities for emerging artists. Animators, often underpaid (with early-career salaries below 2 million yen yearly), bear the brunt, as studios struggle amid exploitation and illegal distribution.
Japan has ramped up anti-piracy efforts, including AI-driven projects funded by the government to detect and shut down illegal sites. Global operations like “Operation Anime” have targeted international piracy rings, recovering billions in potential losses. Yet, camcording remains a persistent issue, especially for blockbusters like Demon Slayer, where leaks can spread rapidly online, spoiling experiences and diminishing revenue.
Public reactions on social media platforms like X (formerly Twitter) reflect frustration. Japanese users condemned the act, with comments highlighting the suspect’s nationality factually but focusing on the crime’s severity, such as calls for strict penalties and deportation. Internationally, discussions mixed outrage with surprise at the backlash, emphasizing cultural differences in viewing piracy. These sentiments underscore a shared concern: piracy erodes the hard work of animators, voice actors, and studios like Ufotable, who pour resources into breathtaking visuals and storytelling.
Why Cultural Sensitivity and Legal Awareness Matter
In an interconnected world, anime bridges cultures, but incidents like this can spark misunderstandings. Mentioning the suspect’s Korean background is based on official reports, but it’s essential to avoid generalizations—piracy affects all nationalities and stems from individual choices, not origins. Japan, known for its strict yet fair legal system, imposes penalties up to 10 million yen fines or seven years in prison for camcording, aiming to deter rather than discriminate.
For international fans, supporting legal streams on platforms like Crunchyroll not only ensures high-quality viewing but also sustains the industry. As Demon Slayer expands globally, with the trilogy’s U.S. release approaching, let’s celebrate ethically.
Conclusion: Protecting Anime’s Future
The arrest of Shim Jun-woo serves as a stark reminder of piracy’s consequences in the anime realm. While Demon Slayer: Infinity Castle continues to break records, safeguarding intellectual property ensures creators can keep delivering epic tales. Fans worldwide play a role—by choosing legal options, we support the vibrant anime culture that unites us. Have you encountered piracy issues with your favorite shows?
